Description
Filter plate, biplane, 200 mm, porosity 2, is a VitraPOR® glass filter disc in borosilicate glass 3.3 for laboratory filtration setups. It has a diameter of 200 mm and a defined thickness of 11,5 mm with a tolerance of ± 0,5 mm. Both faces are ground to deliver exact thickness and a plane-parallel surface, supporting reliable seating in holders and apparatus that need flat contact on either side. Porosity grade 2 suits medium filtration tasks in chemical, preparative and analytical work where controlled flow and mechanical stability are important. The biplane geometry helps consistent mounting when discs must remain true and parallel under clamp or flange load. Offered as a single piece from manufacturer ROBU - Stereon, this VitraPOR® plate is intended for glassware and filtration assemblies that specify borosilicate filter media in porosity 2. Borosilicate 3.3 provides the chemical resistance and thermal behaviour expected of laboratory glass filtration components. Choose this disc where dimensional accuracy, ground plane-parallel faces and a defined pore grade are required for clarification, support filtration or sample preparation steps.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Filter Disc, bi-plane, 200 mm, Por. 2 Thickness 11.5 mm ± 0.5 mm
What is this article?
Filter Disc, bi-plane, 200 mm, Por. 2 Thickness 11.5 mm ± 0.5 mm is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
